Then inimitable @FiedlerAmy reminding us that cardiac surgeons have feelings too! 😂 And educating us on when to call the surgeon and consider a return to the OR in the middle of the night. Communication is key! @UCSFHospitals #critcarecards25 @SocietyOfCCC

Last day of @HoustonShockHSS kicking off with discussions on the real world logistics of delivering shock care and the financial sustainability of shock programs - you can’t do shock well if you don’t review your outcomes and work towards iterative improvement.
